Late-night snacks

Having too many late-night snacks may be affecting your behaviour at work. Employees who reported eating too many late-night snacks were less likely to go the extra mile for colleagues or complete work-related tasks the next day.

Temperature regulation for wheelchair basketball athletes

Research with elite women’s wheelchair basketball athletes has shown playing time can negatively impact body temperature regulation, increasing the risk of heat exhaustion, heat cramps, and heat stroke. Coaches are encouraged to monitor the cooling strategies of athletes with high playing time and encourage all athletes to hydrate during time outs, substitutions, intermissions, and half…

Sodium supplementation beliefs

Many ultramarathon runners believe the consumption of sodium supplements during competition will prevent the symptoms of exercise-associated hyponatremia, including dehydration, muscle cramping, and nausea. However, accumulating evidence suggests supplementing sodium intake above what is consumed in food and drink is generally not necessary, and could be dangerous.

Pre-exercise hydration

While hydration practices during training and competition are important, new research emphasizes the importance of beginning endurance exercise in a well-hydrated state. Athletes experiencing pre-exercise dehydration showed impaired aerobic exercise performance, peak oxygen consumption, and lactate threshold.

Protective effects of nutrition

In American football, measurements revealed youth and college-level athletes experienced anywhere from 100-1,000 head impacts during the season. That trauma can add up, risking long-term impacts on brain health, including cognitive, emotional and behaviour difficulties and dysfunction. Consider the role of nutrition in protecting against repetitive sub-concussive injury.

Risk of Stress Fractures

Stress fractures are observed more frequently in female runners, compared to males. Analysis of women’s perception of risk and behaviors discovered those with a history of fractures increased their training load more quickly, and, despite knowing the benefits, they did not prioritize a balanced diet and complementary cross-training.

Post-Game Snacks

A new study by public health researchers finds the number of calories kids consume from post-game snacks far exceeds the number of calories they actually burn playing in the game. The researchers found the average energy expenditure for children observed was 170 calories per game, while the average caloric intake from post-game snacks was 213…

Cooling Strategies to Improve Performance in the Heat

Whether you are a high performance athlete training for the Olympic and Paralympic Summer Games in Tokyo, or a weekend warrior working on a personal best, learning to manage heat stress should be a priority. Heat stress and fatigue can lead to decreases in performance, influencing a podium finish, or can be the precursor to…
